I quite like a lot of the changes added here. The ones added to untamed will make certain strikes and PvE content more enjoyable.
My only gripe is with Deadeye. Losing the extra range from being knelt kind of defeats a lot of the reason to BE kneeled. Not fully, but sure makes it less appealing, not to mention it makes the whole "sniper" thing silly when it has less range than other weapons.
That said, I do like the addition of being able to walk. Makes kneeling down in more intense situations less punishing- It would be great if there was a special animation to walking while knelt however, not only for flavor, but also clarity.
